Patent GB-190011562-A (GB)
Title: Improvements in and relating to Electric Lamps.
Inventor: HEWITT PETER COOPER
Filed: 1900-06-26
Granted: 1900-12-22
Abstract: 11,562. Hewitt, P. C. June 26. Drawings to Specification. Regulating ; switches.-In the manufacture of a vacuum tube for electric lighting, a high-pressure current is passed through the heated tube during exhaustion, and varied until the required light is given at the desired pressure. A variable pressure for this purpose may be obtained from an alternating or intermittent current supply by connecting the tube in series with an adjustable resistance and the secondary of a transformer between the supply wires, the primary being connected between the same wires. Similar connections, omitting the adjustable resistance, may be used to supply increased pressure for starting the tube, the primary being disconnected from the supply wires after starting. The secondary may then also be shunted by a resistance. On continuous-current supply mains the same connections may be used, an interrupter being inserted in the primary circuit. The interrupter may consist of two lead electrodes immersed in sulphuric-acid solution, and separated by a pot containing small perforations. The connections may be changed automatically when the tube begins to take a considerable current, by tl e transformer core attracting a spring-held armature which carries contacts to open the primary circuit and close the shunt. On a threewire system, the tube may on starting be connected between the outer wires, in series with a resistance and the coil of a magnet, which subsequently attracts a spring-held armature to disconnect one outer and connect the middle wire ; the resistance prevents a short-circuit between the middle and outer wires when the change occurs.

Title: The application of a Barium Compound in the Precipitation of Metals from their Solutions.
Inventor: MARTINO FREDERICK WILLIAM
Filed: 1901-06-19
Granted: 1902-06-05
Abstract: 12,500. Martino, F. W. June 19. Barium sulphocarbide; gold and silver sulphides; sulphuretted hydrogen.-Barium sulphocarbide, a compound of barium, sulphur, and carbon, is prepared, and is employed to precipitate metals from their solutions. The compound is made by fusing two parts by weight of barium sulphate with one of carbon in an electric furnace. A current of about 250 to 300 amperes and about 100 volts is sufficient. The sulphocarbide, when acted upon by water, which is preferably slightly acidified, develops a large quantity of sulphuretted hydrogen, which may be led into a metallic solution to precipitate the sulphide. Preferably, however, the sulphocarbide is used by adding it directly to the metallic solution. It is particularly useful for precipitating the noble. metals, namely, gold from its cyanide, chloride, or bromide solution, and silver from the cyanide or nitrate solution. In the case of gold cyanide, the solution is preferably first acidified with hydrochloric acid, and then the barium sulphocarbide is added. The solution may be used either cold or hot, preferably the latter, as less sulphocarbide is required and the time of the reaction is shorter. In the case of gold chloride or bromide solution, or of silver cyanide or nitrate solution, no preliminary acidifying is necessary.

Patent GB-190121758-A (GB)
Title: Improvements in Processes for Making Milk Extracts resembling Meat Extracts.
Inventor: MIERISCH OTTO
Filed: 1901-10-29
Granted: 1901-12-21
Abstract: 21,758. Mierisch, O., and Eberhard, O. Oct. 29. Food preparations.-Relates to the production of a milk extract which will have a taste similar to that of meat extract. The casein and fat are removed from skim-milk, and then by repeated evaporations the sugar is allowed to crystallize out, the milk during the whole time being kept in a sterilized condition, preferably by repeated additions of a volatile preservative such as formalin. The extract is finally filtered and concentrated, and in this condition it is more particularly useful as an addition to sauces or meat soups and other foods containing meat. In order that the extract may be used for making bouillon without a simultaneous addition of meat, the milk extract, after being slightly concentrated, has fresh disintegrated meat added to it, and the fluid thus obtained is filtered, heated until the albumen coagulates, clarified, and evaporated. In this way milk extract having a flavour of crabs, oxtails, &c. may be obtained.

Title: Process and Apparatus for the Manufacture of Lasts for Boots and Shoes
Inventor: LORANT ALOIS
Filed: 1902-11-25
Granted: 1903-11-12
Abstract: 25,939. Lorant, A. Nov. 25. Casting; milling.-Lasts for boots and shoes are modelled from the feet to which the boots &c. are to be fitted. The foot is covered with a stocking, and under the sole is placed a correspondinglyshaped plate of leather, metal, celluloid, &c. A toe-cap of leather &c., corresponding in form to the boot or shoe to be produced, is placed over the point of the foot, and may be connected to the sole-plate, while specially tender parts of the foot may be fitted with hollowed pads or washers of felt, paper, &c., saturated with a liquid, such as glycerine, which will not dry in the air. An outer elastic stocking is then drawn over the foot, which, when so prepared, may be used directly as a pattern or model in a copying-mechanism for cutting the last ; or, a mould of the foot may be taken and the last cast in the mould, or the cast may be employed as a pattern in the copying- mechanism. Fig. 2 shows a suitable apparatus for taking the mould. The two cylinders 2 are hinged to the base-plate, and are closed at the outer ends by discs 3 also hinged to the base. Diaphragms 6 of india-rubber &c. are fixed to the discs 3 by means of clamping-rings, and the cylinders 2 are provided with annular packing-pieces, which fit round the leg of the person when the foot is in position in the apparatus, as shown. An easily fusible metal, liquid gypsum, cement, stearin, wax, &c. is introduceu through the funnels 7, and forces the diaphragms 6 inwards against the foot, so that, when the material has set, two half-moulds of the foot are obtained, which are then used to cast the last or pattern. Fig. 7 shows a form of copying- apparatus. The style 81 is mounted in the sleeve 80 on the.wheel 78, and is caused by the bevel-andscrew gearing 83, 83', 84 to travel in a helical path around the foot or pattern 86. A lever 89 on the end of the spindle of the style is connected to a similar lever pivoted on the wheel 78, the latter lever carrying a copying-style or rotary cutter 87, whereby the oscillations of the style 81 are scribed in the form of a groove 102, Fig. 10, on a strip 101 of metal &c., driven by clockwork &c. in contact with the cutter. The strip 101 is then transferred to a second apparatus, wherein a style is made to follow the groove 102, and imparts corresponding oscillations to a rotary cutter, which cuts out the last to the form of the foot or model 86, Fig. 7. The rotary cutter 87, Fig. 7, is driven by an endless belt, which is passed around a pulley on the cutter spindle, suitable guide-pulleys, and the fixed pulley 92.
